Tailscale VPN

Tailscale can be used to access your BliKVM from the public internet. It is a convenient and free networking tool for setting up a small VPN network. This document provides an example for accessing your BliKVM over the internet, but you can also use Zerotier or other VPN solutions. The following is a basic example, and for any specific settings or functionalities, please refer to the Tailscale documentation.

BliKVM Installation

First, make sure that your system has read-write access. If it's a read-only system, use the rw command to make it writable. Then, proceed with the Tailscale installation by running the following command:

curl -fsSL https://tailscale.com/install.sh | sh

Adding BliKVM to your Tailscale Network

Register an account on the Tailscale website and generate your own keys in the settings. On the BliKVM terminal, use the following command to add BliKVM to your Tailscale network:

sudo tailscale up --authkey=your-auth-key --accept-routes

If everything goes well, you can run ip addr show tailscale0 on the BliKVM terminal to view the IP address assigned by Tailscale for the virtual network.

Here's an example output:

3: tailscale0: <POINTOPOINT,MULTICAST,NOARP,UP,LOWER_UP> mtu 1280 qdisc pfifo_fast state UNKNOWN group default qlen 500
    link/none
    inet 100.126.223.28/32 scope global tailscale0
       valid_lft forever preferred_lft forever
    inet6 fd7a:115c:a1e0:ab12:4843:cd96:627e:df1c/128 scope global
       valid_lft forever preferred_lft forever
    inet6 fe80::8955:99dc:4e7d:b08b/64 scope link stable-privacy
       valid_lft forever preferred_lft forever

The IP address, such as 100.126.223.28, can be used to access the BliKVM web interface from your host machine.

Host Installation

Download and install Tailscale from the Tailscale website on your controlling host machine. Log in with your Tailscale account, and then you can check the Tailscale admin page to verify if both your machines are online. Once they are online, you can use the following address to access BliKVM from your controlling host machine:
